Sliding Wear Behavior of Severely Deformed 6061 Aluminum Alloy by Accumulative Roll Bonding (ARB) Process

Abstract:

Sliding wear behavior of severely deformed 6061 aluminum alloy sheets by accumulative roll bonding (ARB) process subjected to dry sliding wear at different loading and sliding velocities was investigated using a pin on disc wear machine. The sheets were processed up to five ARB cycles in order to induce a high strain (~ 4.0) to the samples. EBSD results showed that after five cycles of ARB, sheets were found to contain ultra-fine grains with high fraction of high angle grain boundaries. Wear was continuously monitored by measuring the weight losses and morphologies of worn surfaces by scanning electron microscope (SEM), and a model for the wear of the ARB-processed samples was proposed.
